WHEEL-SECURING MEANS.

To all whom it may concern:

Be it known that I, RUDOLPH ERDMArmV BERGMANN, a citizen of the UnitedStates, residing at Salt Lake City, in the county of Salt Lake and Stateof Utah, have invented certain new and useful Improvements inVheel-Securing Means; and l do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to wheel securing means and has for an object toprovide improved means for securing a hub upon the axle.

Vhile the present invention is adapted especially for use in connectionwith vehicles'and vehicle wheels it will be obvious that it will beoperative for and in association with wheels and for various purposes.

With these and other objects in view, the invention comprises certainnovel constructions, combinations and arrangements ot parts, as will behereinafter fully described and claimed.

In the drawings:'Figure 1 is a longitudinal'section view of thefastening means. Fig. 2 is a View of the fastening means in elevation.Fig. 3 is a perspective view of the securing spindle.

Like characters of reference designate corresponding parts throughoutthe several views.

As shown in the drawings an axle 10 is shown tubular or hollow providinga bearing for the hub 11. The hub 11 may be of any ordinary or approvedconstruction and the axle 10 may be a short axle secured as at 12 to aframework of any kind or it may continue entirely across the vehicle asfound expedient.

lVhatever the construction of the axle the bearing stud upon which thehub rotates is of substantially equal length with the hub and a spindle13 is inserted within the bore of the axle and is provided with a headlet large enough to prevent displacement of the hub from the axle.

The spindle 18 is provided at its extremity with a pointed or conicalend 15 with a groove 1G adjacent the base of the cone 15.

Extending within an opening 17 is a pin 18 held to seat by any approvedresilient means applied in any approved manner here shown specificallyas a spring 19 embrac- Speccaton of Letters Patent.

ing a portion 20 integral with the pin 18 joined by means of theconnecting member 21. rl`he arrangement as shown is a convenientarrangement extending as it does through the axle and forms a bearing toprevent lateral play of the pin and to insure its return properly toseat when released.

It will be obvious that with the parts associated as shown in thedrawings the hulo 11 cannot be displaced from the axle as the head 14prevents such displacement and by reason of the engageinent o1 the pin18 with the groove 1G the spindle 13 carrying thehead 14: is preventedfrom becoming displaced. When, however, it is desirable to remove thehub the spring 19 is compressed by moving the pin 20 thereby lifting thepin 18 from the groove 1G whereupon the spindle 18 may be withdrawn fromthe axle of course withdrawing the head therewith after which the hubmay be removed from the axle without diliiculty. In returning the partsto place the hub is irst placed in position upon the axle whereupon thespindle 13 is entered in the bore of the axle and pushed to seat, theconical extremity causing the pin 18 to ride up the incline and to snapautomatically into the groove 16 whereby such spindle is held inposition. As it is desirable that the disk 14 remain stationary a holeis provided in the spindle 13 within the groove 16 into which the pin 18is inserted by the action of the spring when the spindle is rotated, andwhich maintains such spindle and disk against rotation.

What I claim is 1. In a wheel securing device, a hollow axle, a spindleinsertible within the hollow axle, means carried by the spindle forpositioning a hub, a latch carried by the axle and resilient means forholding the latch in engagement with the spindle.

2. In a wheel securing device, a hollow axle, a spindle insertiblewithin the axle, and provided at one end with a head and at the oppositeend with a recess, and a springpressed detent carried by the axleadapted to engage the recess.

3. In a wheel securing device, a hollow axle, a spindle insertiblewithin the hollow axle and provided with a head larger in diameter thanthe diameter of the axle, and with a recess at the end opposite thehead, and a resiliently depressed detent carried by the axle adapted toengage within the recess.

4. In a wheel securing device, a hollow axle, a spindle insertiblewithin the axle and provided with a head at one end greater in diameterthan the diameter of the axle, and withits end opposite the head formedwith an incline, and a depression, and a detent carried by the axleadapted to ride up the incline and engage within the recess.

5. In a wheel securing device, a hollow axle,.a spindle insertiblewithin the hollow axle and provided at one end with a head greater indiameter than the diameter of the axle, and at its opposite end providedwith a conical extremity and a groove adjacent the extremity and aspring-pressed detent carried by the axle adapted to ride upon theconical extremity and snap automatically within the groove.

6. In a wheel securing device, a hollow axle, a spindle insertiblewithin the axle, means carried by the spindle adapted to position a hub,a bar extending through the l axle, a detent carried by the bar andadapted to engage the spindle, andresilient means for positioning thebar and detent.

7. In a wheel securing device, a hollow axle, a spindle insertiblewithin the axle and provided at one end with a head .greater in diameterthan the diameter of the axle and at its opposite end with an inclinedextremity and a recess, a U-shaped rod extending through the axle andhaving one end formed into a detent adapted to engage the recess, and aresilient member carried by the opposite end adapted to hold the detentyieldingly to seat.

In testimony whereof I aliix my signature in presence of two witnesses.
